Forum: etree Subject: Re: MP3s derived from FLAC have NO Song/Album etc Metadata

Hi, this is for a netlabel item, not a Live Music Archive item it appears.

you seem to have only uploaded one flac. are there others?

the mp3 will only have the tags when the metadata is filled out from the original time of submission.

I will re-run the derive task to see if that helps.

Yes, I posted in this forum because I noticed that one of the LMA downloads did have metadata despite being derived from FLAC. I stopped uploading flac after I received complaints that the derived mp3 files were lacking metadata. I thought there may have been some trick to this, such as using ID3 tags instead of vorbis tags. Unfortunately the Derive did not work. I uploaded a single file as a test case so ONE mp3 file would be lacking metadata instead of ALL. However I am looking to re-add flac as an option to my releases if I can get the metadata to display correctly.

I just uploaded a "test" to see if the metadata would be present from a derived flac upon initial upload. There was no metadata. I often use custom tags IN ADDITION to standard tags, so I did a test removing custom tags and genre then Derived. But this didn't work either. I use the official FLAC encoding .exe as well so I'm really not sure where I'm going wrong.

Here is my test item http://www.archive.org/details/TestItem_627

I've experienced the same thing and fought with it forever until I accidentally stumbled upon how it is done automatically. I was tagging my .flac's to perfection only to have the derived .mp3's basically tagless. Once I figured it out, it's a very simple process and my .mp3's are tagged perfectly (although this probably won't support your custom tags you speak of).

What I have found that works flawlessly is the following (see: http://www.archive.org/details/bajadunes2012-02-10.sbd.r16.q3hd.matrix.flac24 as the example I'm basically quoting from).

1. Make sure your setlist .txt file is perfectly documented like the one at the above URL (go to the bottom of the page and click on the bajadunes2012-02-10_Matrix.txt link under "Other Files). You'll hopefully notice that there's a simple "See our Facebook page at: xxx" at the top and then the next batch of text is the actual setlist labeled like:

Set 1:

1. xxxx
2. xxxx

Set 2:

1. xxxx
2. xxxx

2. When the LMA "ingests" your files and you get to the page where you document all the metadata, it seems to look at the setlist txt file to know what the individual track titles should be.
3. It does NOT (as you and I have both realized) look to the tags on the .flac files themselves. So in other words, once you upload the files and get to the metadata page, your .flac files are about halfway described because they already have their titles (yay!). They WILL be missing the Band as well as the Album text.
4. On the same metadata page where you discover that the individual flac files ARE titled correctly (because you uploaded a perfectly documented setlist .txt file!), there are two buttons that will populate the metadata for Artist/Band and Album. Click them both (don't worry! Click 'em!) and you'll see the Artist/Band for EVERY .flac file get populated as well as the "Album" (e.g., the gig date/venue - like: 2012-02-10 Live at Bookwalter Winery (Matrix)).
5. Once you are satisfied that the .flac's are adequately labeled, click Submit and then the derive process will take over and, based on all the wonderful metadata in the metadata page, will tag the newly derived .mp3 files correctly.
6. The reason I don't think you can sneak in your custom tags is because it seems this process is somewhat fixed in stone. BUT...gosh...look around in the metadata page (or elsewhere??) because you might stumble upon a way to insert your custom tags.

Best of luck!

Sincerely,

Kevin B. Selby

Hi Kevin, thanks for the reply. I uploaded a txt to my new test item here http://www.archive.org/details/Testitem_470
However I didn't have luck populating metadata on it.

When you say the following:
"On the same metadata page where you discover that the individual flac files ARE titled correctly (because you uploaded a perfectly documented setlist .txt file!), there are two buttons that will populate the metadata for Artist/Band and Album."

Do you mean this page? http://goo.gl/dCJ6R [link to screenshot]. I don't see the option on here, maybe its different vs LMA releases. Thanks for your help!

Yes, that's the metadata editor. For LMA items, we require an informational file in .txt format; it's supposed to contain a track listing among other things. If it's properly formatted, the system can parse the track listing and pull the titles in.

The buttons that Kevin mentions, for auto-population of the "Creator" and "Album" fields, do not exist for other audio items, unfortunately, so those must be filled out by hand.

Those four fields - Title, Creator, Album, and Track - are the only ones that I'm aware of that can be used to tag derivative files. You can add custom fields to the metadata of your page, with the "Add another field" link next to the "Submit" button at the very bottom, but it's not clear whether they will apply to the individual tracks on a tagging level. Hopefully someone else can chime in who has a higher-level view across more audio collections than I do.

See this tutorial: http://ia700202.us.archive.org/3/items/uploaded/greenone-LMA_Uploads_082609.pdf?cnt=0

specifically, page 5 where it shows a shot of a typical track and then mentions the buttons to push to populate Album and Creator (e.g., Band).

I have always had it populate correctly when I submit the items and it initially parses them. You seem to have added the txt file "after the fact" and therefore you MIGHT have needed to go to the metadata page again and populate the fields for the .flac file AND you might have ALSO needed to them go to the page where you can "Re-Derive" the .mp3. This triggers the process to re-encode the .mp3 and because you would have fixed the metadata, it would have used the data for the tags of the .mp3. Once you do this a few hundred times you'll actually be pretty comfortable with the various steps involved.

Best of luck!!!
